Cressall’s range of standard portable load banks is designed for testing AC and DC systems, including batteries, uninterruptible power supplies (UPS) and standby generators.
All units are fan-cooled, which helps to ensure a compact design. The fan supply is taken from the test load itself or from an auxiliary supply of 110 or 230V AC, according to model.
Units are fitted with over temperature protection. To reduce weight enclosures are manufactured from aluminium and fitted with handles and where required have castors to ease manoeuvrability. Load banks are supplied with one cable and connector.
All units can be operated at voltages lower than their nominal rating; power is reduced accordingly.
